| 摘 要： | 长江流域的河流健康问题已经引起社会各界的广泛关注.选择健康长江评价指标之一的河道生态环境需水满足程度进行研究.将长江流域的河流分为3种类型,针对不同的河流(或河段)类型采用不同的方法计算河道生态环境需水量.从生态环境缺水量的角度对河道生态环境需水满足程度重新定义,以适于长江流域可能季节性缺水的特点,并利用来水和用水资料,计算了各河流(或河段)的满足程度,最后根据计算结果对其健康状态进行评价.研究结果表明目前长江流域仍处于较为健康的状态.

| Abstract: | In this paper,the problem of satisfactory ratio of environmental water demand of river Channels in Yangtze River basin was studied.The rivers in Yangtze River basin were classified as 3 types by the healthy river standard.Different methods should been applied to calculate environmental water demand in different type of rivers.And a new definition of satisfactory ratio of environmental water demand was introduced to calculate and assess the rivers in Yangtze River basin.The result demonstrates that Yangtze R... |
